@brazoshack Just because you have someone with the mammon on your friend list does not improve your chances of getting one. Like I said it's all random and luck. I got both my Mammon w/ elixir from guest. Just use the "Update Data" function under the save option. The game searches for people around the world and adds them in your guest list. If your lucky they will have the right Mammon and you get it from them. It's nice to have the Mammon, but you don't need it to beat the game. I didn't get mine till I was almost done with the game which I mostly had everything bought. Getting friends is mostly to summon them and deal massive damage to those really hard bosses like in chapter 8.

@geass2012 The only way you can tell if it has the elixir is by stealing it with a Thief job or ability. It is not a drop. There are two kinds of Mammon one with ether and one with elixir. Once you get the right one 'Protect' it so it won't disappear and put it on 'Send' so others can get it. The trick is to have one person with steal ability (with 'Rob Blind' support so you can steal two at a time) steal it from her and the others flee so you can keep stealing from her. Make sure the stealer has the fastest speed of the group and you can auto-battle her for fast stealing.
